Title: Light source for exposure device
Inventor: AKETAGAWA MASATO
IPC: H01S3/225
Filed: 1987-05-13
Abstract: PURPOSE:To prevent a resolving power from reducing due to a chromatic aberration by a method wherein the absolute value of the wavelength of a laser beam is detected, the oscillation wavelength is fixed within a constant range to stabilize and when the laser beam is used in an exposure device, the deviation amount of the position of focal point is made the smallest. CONSTITUTION:A laser beam which is emitted from a KrF excimer laser 1 is incided in an exposure device by a half-mirror 3, one side of reflected laser beams is reflected by a half-mirror 8 to inside in a photo detector 9 and the other side is transmitted and incided in a see-through type hollow cathode lamp 4 with a cathode made using Fe. When the Fe is used to the cathode of this lamp 4, the line spectrum of the Fe is luminesced and a line spectrum of a wavelength of 248.33 nm can be obtained. The wavelength of the laser of a narrowed band is moved in the direction shown by an arrow A and is turned to the line spectrum of the Fe. A controller 10 compares the value of the maximum opto-galvanic current at each laser beam power value being stored with the value of the present discharge current and controls a wavelength finely adjusting unit 2 in such a way that an opto-galvanic effect is always a maximum. The wavelength not only can be fixed to the line spectrum of 248.33 nm of the Fe, but also the stability of the wavelength can be held within the width of the line spectrum of the Fe.
